What class do you want to be in? I am getting adjustable Konis before next season, and some Azenis, but cannot do much else unless I leave G Stock (which I don't want to do yet). I would suggest a good performance alignment (as much camber as you can get and some toe-out in the rear to get more rotation). If you have, or will have, coil-overs I would suggest the alignment and getting corner-weighted. Then take it out to a wide open space and play with it, and see what settings suit your style the most.
I would personally love to get my rear end looser. I have a hard time getting it to rotate and therefore am struggling with understeer throughout the course. But i am not sure what more to do and stay in G stock...
